: Urinary tract infection (UTI) is one of the most common conditions during pregnancy. The aim of this study was to assess the prevalence of germs and the antimicrobial susceptibility profile in urine culture isolates from pregnant patients treated at a tertiary maternity hospital in Porto Alegre, Brazil.
: A cross-sectional, retrospective and descriptive study was carried out at Hospital Fêmina, a leading institution in prenatal, birth and postnatal healthcare in the city of Porto Alegre, Brazil. A total of 482 microbial community results were analyzed out of 1,558 positive urine cultures of pregnant women in all gestational ages treated at Fêmina Hospital between January 2007 and July 2013.
The susceptibility pattern presented in this research shows that the choice for UTI treatment during pregnancy should be nitrofurantoin (for uncomplicated infections) or second-generation cephalosporins such as cefuroxime (for uncomplicated and complicated infections), over ampicillin, first-generation cephalosporins and sulfamethoxazole/trimethoprim.
: Empirical treatment for UTI in pregnancy should be started according to the susceptibility patterns described in the literature and re-analyzed after the results of the urine culture.

PURPOSE: to verify the occurrence of colonization by Streptococcus agalactiae in pregnant women attended at the prenatal outpatient clinic of the Teaching Maternity Hospital of Rio de Janeiro University (UFRJ) and to evaluate the susceptibility of the isolates to antimicrobial agents. METHODS: a total of 167 pregnant women between the 32nd and 41st week of gestation, regardless of risk factors, attended at the antenatal clinic between February 2003 and February 2004, were evaluated. The vaginal/anal material, collected by the same swab, was inoculated in Todd-Hewitt broth to which nalidixic acid (15 µg/mL) and gentamicin (8 µg/mL) were added, with following subcultures onto sheep blood-agar. Identification was carried out observing colony morphology and beta-hemolysis type on blood-agar, catalase, cAMP, and serological tests. The antimicrobial susceptibility testing used agar diffusion and agar dilution methods. Statistical analysis was performed by the chi2 test with the level of significance set at p<0,05. RESULTS: the frequency of colonization was 19.2%, with no significant differences when age, number of gestations, number of abortions and the presence or absence of diabetes mellitus were compared (p>0.05). All 32 isolated strains were susceptible to penicillin, cefotaxime, ofloxacin, chloramphenicol, vancomycin and meropenem. Resistance to erythromycin and clindamycin was detected in 9.4 and 6.2% of the isolates, respectively. CONCLUSIONS: the relatively high incidence (19.2%) of colonization by S. agalactiae among the evaluated pregnant women and the recovery of antimicrobial resistant strains, especially those recommended in cases of penicillin allergy, emphasize the importance, for a correct prevention of neonatal infections, of detecting colonization at the end of pregnancy and evaluating antimicrobial susceptibility.
